PCT No. PCT/IE94/00050 Sec. 371 Date Apr. 17, 1997 Sec. 102(e) Date Apr. 17, 1997 PCT Filed Oct. 17, 1994 PCT Pub. No. WO96/12191 PCT Pub. Date Apr. 25, 1996Stabilizing medium for urinary alpha GST contains a stabilizing amount of a non-enzyne protein, such as a mixture of equal amounts (w/v) of bovine serum albumin and gelatin hydrolysate, chelating agent and a buffer, such that the medium has a pH in the range 7.0-7.5, the medium being effective to prevent loss of alpha GST immunological activity. The stabilizing medium can be used to store urine samples at temperatures of the order of -20 DEG C. without any loss of alpha GST immunoreactivity of the type observed in samples which are stored without such a stabilizing medium. The stabilizing medium also improves the immunoreactivity of alpha GST when added to fresh urine which is stored temporarily at 2-8 DEG C. prior to assay for up to two hours.
